Sharing Data between Applications

On desktop computers people have to enter identical data innumerable times. Each application requires that the data be put in its own format: you enter names, phone numbers, and fax numbers in a computerized address book, only to have to reenter the same information in your fax application when you want to send a fax. Copy, paste, and importing and exporting, while a solution, are not the best; it would be better if your fax application used the same information your address book uses.

With the Newton, users enter information only once. When you send a fax, your Newton fax application gets the name and fax number from the "Names" soup. To facilitate this model of sharing data, Newton applications can do all of these:

Reading Data from Another Soup
Adding Slots to Other Soup Entries
One Copy of Data
Change Notification
